<p class="MsoNormal">Hi Michel,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">After the system idle for a while, the screen will be off(blank out) and AMD GPU will be put into a very low power state(BACO) due to runpm.<o:p></o:p></p>
<p class="MsoNormal">However, I found there will be still DRM IOCTLS(which I paste below) coming regularly.<o:p></o:p></p>
<p class="MsoNormal">And those IOCTLS(especially those for AMDGPU) will wake and back our GPU into normal state.<o:p></o:p></p>
<p class="MsoNormal">To me, that’s a little weird as the system was just left there for nothing. I do not know what and why these DRM IOCTLs come for.<o:p></o:p></p>
<p class="MsoNormal">Per Alex, it seems “<span style="font-size:12.0pt;color:black">desktop environments poll for display updates at regular intervals”. Do you also think so? Or any other insights?</span><o:p></o:p></p>
